If you want to take action to help protect coral reefs, wear a rash guard instead of slathering on the sunscreen. Recent studies have shown that chemicals in sunscreen, like oxybenzone, can be harmful to coral reefs. Corals are tiny soft-bodied animals called polyps. Their food is provided by photosynthesis from the algae that lives within the polyps. The chemicals in sunscreen can cause the corals to become ill and die.
What can you do to help the corals stay healthy? Use sunscreen WITHOUT oxybenzone, wear a rash guard or other protective clothing. They are more reliable and effective at protecting skin from the sun's rays. No constant reapplying necessary!
